To find the radius, we can use the formula for the circumference of a circle:
C = 2πr
Given that the circumference is 7,459 miles and π is 3.14, we can substitute these values into the formula to solve for the radius:
7,459 = 2(3.14)r
7,459 = 6.28r
r = 7,459 / 6.28
r ≈ 1,187.7 miles
Therefore, the radius rounded to the nearest hundredth place is 1,187.7 miles.
So the correct answer is:
B. 1,187.7 miles
The approximate circumference of a circle is 7,459 miles. What is the radius rounded to the nearest hundredths place? Use 3.14 for PI and express your answer to the tenths place.
A. 2,375.5 miles
B. 1,187.7 miles
C. 3,729.5 miles
